A storm system created up to 60 mph winds and blowing dust Monday that caused multiple-vehicle crashes on I-10 near Picacho, authorities said.
Overnight, the Tucson area got a rainstorm, and a slight chance of rain was predicted for today. There's a chance of snow in the higher elevations, cooler temperatures and breezy conditions, the National Weather Service said.
On Monday, two tractor-trailer rigs jackknifed, and two passenger vehicles were involved in a crash on westbound Interstate 10 at Milepost 213 near Picacho around 2 p.m., a state Department of Public Safety spokesman said.
Four people were taken to Tucson-area hospitals with non-life-threatening injuries, DPS Officer Raul Molina said.
One rig hauling produce rolled and blocked an eastbound lane on the interstate, Molina said. That crash and other nonserious wrecks, including a chain reaction crash near Milepost 212, were related to blowing dust, authorities said.
Motorists along I-10 between Phoenix and Tucson dealt with dust and wind gusts up to 60 mph, the Arizona Department of Transportation reported. Low visibility also closed a stretch of Interstate 40 east of Flagstaff in Northern Arizona for several hours Monday.
Southern Arizona between Tucson and the New Mexico line also experienced strong winds, but no crashes were reported.
Wind gusts in Tucson reached 49 mph, the weather service said.
Today's high in Tucson is expected to be in the mid-60s and the low in the 40s, according to the weather service. Winds are expected to reach 15 to 25 mph by this afternoon.
Highs are expected to go up on Wednesday and Thursday.
Overnight and into this morning, Mount Lemmon was expected to receive some snow, with the snow level dropping to 6,500 feet, the weather service said. There is a 50 percent chance of rain in the Santa Catalina Mountains today.
